Nettet1 Answer. Model-free resampling of time series is accomplished by block resampling, also called block bootstrapping, which can be implemented using the tsboot function in R’s boot package. The idea is to break the series into roughly equal-length blocks of consecutive observations, to resample the block with replacement, and then to paste …

Nettet13. jun. 2024 · I am currently trying to Block-Bootstrap my Stock-return data in Python. I am doing that to generate synthetic data.
